To all whom t may concern.'

Be it lmown that I, HARRY C. JoNEs, a citizen of the United States, anda resident of Larchmont, Westchester county, New

-York, have inventedcertain new and useful' Improvements in CameraApparatus, of which the following is a specification.

My invention relates to improvements 1n cameras, and I have especiallydesigned my improvements with respect to a camera such as is used in themaking of line negatives or half-tones.

, One object of my invention is to provide. "an improved apparatus bymeans of which space on negatives or any form of plate may be saved andmore economically used, 1n which 'the time necessary to produce a givennumber of half-tones or plates may be l greatly decreased, and in whichthe amount 1 provide an apparatus in which .ample space. is given for aplurality of objects, and so of handling and materials used may bedecreased and made more economical.

Affurther object of my invention is to arranged that they may bephotographed in rapid succession;

l. A further object of my invention is to provide a single plate holderfor a single `sensitized platev and a plurality of lenses co operatingtherewith, each independently focusable with respect to the plate andadapted to lproduce 'independent images on the plate at different partsthereof, and'to prol vide independent screens for each image and meansfor independently adjusting them toward and from the plate, and also to'provide means whereby the plate may be moyed with respect tothepartitions so as to pre- 1 vent the passage off-light from one section lof the plate to another;

' Further objects, features and advantages will more clearly appear fromthe detailed description given below taken in connection d with theaccompanying drawings which formA ai part of this specification.

In the drawings, Figure 1 is a top plan view partly in section showingan apparatus embodying my improvements in one form. Fig. 2 is a verticalsection taken Qn the line 2-2 of Fig. 1. Fig. 3 isa vertical sectiontaken on the line 3-3 ofv Fig. 1. Fig. 4 is a vertical section takenon'the line 4-'4 of Fig. l. Fig. 5 is a diagrarnillustrating certain ofmy improvements embodied in modified form.

Referring to Figs. 1 to 4 inclusive, 1 represents a suitable framewor'hupon which.

lare slidably mounted .three independently movable lens carrying heads2, 3 and 4. These lens carrying heads carry respectively lenses 5, 6 and7. The lens carrying heads are movable horizontally by means of screwshafts 8, 9 and 10, respectively, by means of' hand wheels 11, 12 and13, in order to rop- I erly focus the lenses independently o oneanother. The frame 1 carries a slidably mounted object holder 14,whichis adjusted at ditl'erentv distances from lthe lens 6 by means of ascrew shaft 15, operated by a hand wheel 16.. Rigidly connected with thelens carryingv heads 2l and .4 'are slidably mounted frames 17 and 18,upon which are slidably mounted object holders 19 and 20,

adapted ,to move in a horizontal direction but at right angles to thedieCtOn in which the object holder 14'moves.

The object holder/s 19 vand 2O are moved by means of screw shafts 21`and 22 respectively, which screw shafts are provided on their innerendswth bevel gears 23 meshingwith bevel gears 24, splined to shafts 25and 26,'

operated by hand wheels 27 and 28' respectively. It will thus be seenthat the bevel gears 23 and 24 are carried bythe frames 17 and 18, sothat they are always in mesh no matter whatposition the frames 17 and 18occupy with respect to the frame l. The lenses 5, 6 and 7 may beadjusted to different positions vinthe lens carrying heads 2, 3 and4,'in any well known orsuitable manner. v f

30 re resents a suitable plate holder provided with a back 31, sidepieces 32, top and bottom'pieees 33 and 34, and a front slide ,35.Theplate holder. is adapted to contain a single sensitized plate 36placed therein in any well known manner. The plate holder 30 is adaptedto have thefront ed es of the sides 32 and of the top 33 slide etweenmembers 37 and 38 which are rigid with the frame 1, thusforming alighttight joint between the plate holder and the frame,4 when the plate'holder is placed. in position, as shown 'in the drawings. .The members38 form partitions for determining the area exposed by each of thelenses 5, 6 and 7 respectively. The partitions 38 are connected with thelens carrying heads 2, 3 and 4 byV means of collapsible walls 40,

sides of the screens 41, 42 and 43, one for each lensn These screens arepreferably glass plates suitably etched with lines crossing one anotherin order to form the necessaryn lines on the negative or other plateoperated upon,` rl`hese screens are carried rigidly with racks 4A, 45and 4:6, which are moved by means of gears 4C?, 48 and e9, respectively,rlhe gears 4l?, 4-8 and 4:9 are rigidly connected with shafts 50,51 and52, which are provided at their outer ends with' handles 53, 54: and 55,so that any one of the screens 4:1, 42 or d3 may be moved toward theplate 36 independently, and properly adjusted with respect thereto.After the slide has been withdrawn from. the plat/e holding means theholder 3Q and the plate 36 may be moved forward, the top, and latehold/er sliding between the' members 3 and 38, as above esplaniedc lin'order to force the plate holder and plate. forward l provide a bell.crankJ lever '56, with a handle 57, adapted. .to operate upon the backof the plate holder at 58, so. that uponlitting the handle 57 the plate'and late holder are forced inwardly, as shown 1n dotted lines in`l `ig3, thus bringingthe plate 3d into close proximity with the front edgesotthe partitions 38, so that there is no danger of any light lea-hingaround these partitions so as to strilre one section or part ofthe platewhen another part is being exposedo In order that the objects placedupon the' object holders i9 and 2O may have images thereof properlyproduced upon the plate '36 by means of the lenses 5 and 7, l provideyrisms (il and 62 adjacent the lenses 5 and 7, so that the li ht rayspassing from the objects, at l9an 20, are deflected through the lenses 5afnldv7 so as to produce images thereof upon the plate, through thescreens 41'a11d 48. Any Well known means may vbe substituted for theprisms 6l and A62,

which will properly change the direction ot the light rays., Thus itwill 'be seenthat I provide for one or more of the lenses means fordeviating or bending the axial line ,of light of the lens wherebyobjects placed at 19 and 20 may have their images lproduced at theproper places' on the plate 36. Itis not necessarythat the axial line`of the lens or lenses be bent at right angles, since any suitable anglemay be used. lit is important, however, that the axial line ofA one ormore of the lenses be deviated, as explained, in order that largeobjectsfmay be simultaneously focused on the holders 14, 19 and 20,without interfering. with'one anothere By thus distributing cthe objectholders 1d, 19 and 20 in different' directions and providing means fordeviating the axial line of' rays from the objects to the lens theobjects are better acconnnodated.`

It will thus be seen that l have provided noname an improved form ofapparatus by' means of which a plurality of objects may be set up andadjusted for photographing each independentlyv of the` other, and eachmay be independently focused with respect to a single sensitized plate.That is, a number of objects may be preliminarilyfocused and thenrapidly exposed, one alter the other, upon d1i`erent portions of 'thesame sensitized plate. By this arrangement a number of negatives orimages 'may be developed by a .single operation.

lt often happens that thesize of each image which it is desired toproduceis comparatively small, and since for convement handling it isnecessary'to have-a plate of a size much larger than 1s necessary. toaceommodate such small images, in thel ordinary torm ofapparatus a great,deal of this 2 .plate is wasted as well as materials; with which it isdeveloped, sothat by exposing a number of images on diferentportions ofthe plate not only is the wholearea of the 'plate' economically .usedbut a l' number of half-tones or images' arel 'all' produced by onesingle operation., which in old-forms of devicesit tooka''c(neresligondini,Lelyl large number of operations' to' prrnlu'oe;, yln the use of wet plates in such cameraisg'it is vim-` portant that vtheplate be developedwithin the camera, so that all 'of the exposures ashort space of time after' being put 1n 1 must be made within. av'reasonably short that the late only needsto be. in the camera a very s'ort space of-tlme, and time does the vai 1,05 1n quick succession, orsimultaneously, so;

not have to be Wasted to focus one object after another has been eXosed, and so on.

Referrin to Fig.' 5,' I t ere show a dlagram mere y illustrating certainof my improvements in a 'mod iiie'd form. there show four objects 71,'72, 73 and 74, adapted to cooperate with independent lenses`75,

76, 77 and 78, which produce Correspondingv `imagesuipon a singlelsensitized lplate 79.

lt will be noticed that the objects 71 to 74 inclusive, aredistributedabout in diiierentdirections in order that more space may behad for the objects,- andyet the rays from" them cre properlyconcentrated upolnfa smaller" space on the plate 79.` In order todeviate the rays or the axial line of rays from the objects 71 and72, 73and 74, so as to cause the rays to properly strike the' plate 79, lprovide prisms -80, 81, 82 and 83 in the path of the rays in the frontof the plate 79. The arrangement shown-in Fig. 5 is not a preferredform, but merely `illus-- trates one method of deviating or bending therays so that the axial lineof rays from the object is bent in order tobetter accommodate the objects.

Although I have described my improvements in great detail and withrespect to certain particular embodiments thereof, nevertheless I do notdesire to be limited to such details vexcept as clearly specified in theappended claims, since many changes and modifications may well be madewithout depart-ing from the spirit and scope of myinvention in itsbroadest aspects.
